Given numbers are 428, 264, 570, 663

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 663 are 3 x 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 428, 264, 570, 663

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(428, 264) = 28248

GCD(428, 264) = ( 428 x 264 ) / 28248

= 428 / 264

= 428

Step2:

LCM(4, 570) = 1140

GCD(4, 570) = ( 4 x 570 ) / 1140

= 4 / 570

= 4

Step3:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

So, Greatest Common Divisor of 428, 264, 570, 663 is 1
